1-(Naphtho[1,2-b]furan-2-yl)-2-(isopropylamino)ethanol (II) and 1-(naphtho[2,3-b]furan-2-yl)-2-(isopropylamino)ethanol (III) show low beta-adrenergic blocking activity and unlike the naphtho [2,1-b]furan derivatives (1,2) do not appear to give rise to metabolites with high beta-adrenoceptor inhibitory properties. The inclusion of the --OCH2-- moiety in an aromatic nucleus larger than the benzofuran system (bufuralol, Ro 3-3528) caused loss of the biological activity.
